I've also read some articles about making sure that you have maximum fuel
flow during takeoff to ensure adequate cylinder cooling. Using the boost
pump is supposed to help achieve this.

For me it's:
* Takeoff
* Tank Change
* (long final) Landing
Regarding starting, my engine likes 5-6 seconds of prime when cold. 10
seconds was too long and 3 seconds was not enough.
Once started (even for 2 minutes) my setup requires a flooded start
procedure which seems to work every time.
As you said there may be no one "right" answer but I do PERSONALLY believe
there are wrong answers like not using the boost pump of takeoff and short
final.

Great responses on the approach speed, very helpful. My second item that
seems to draw some differing approaches and I suspect there isn't one right
answer is the use of the fuel pump.
I've seen some who use it strictly on starting to those that use it
liberally in the IMPORTANT zones, i.e., takeoff, descent, approach, landing.
I know the latter is for safety, but would love to hear technical reasons
why its a good idea.
Also, I've seen some recommend 1-3 seconds on pre start to 3-10 seconds. I
suspect the veterans listen to the fuel pressure build up and don't rely on
their watch?
Anyone care to share your boost lore?
